Signaling/quiet bit in NaN on MIPS architecture is opposite of the same bit on ARM/x64: on MIPS it is zero for quiet NaN whereas it is zero for signaling NaN on other configurations.\r\n\r\nI couldn't find in the specs: does WebAssembly specification mandates that quiet NaN has a specific bit in the signaling/quit bit or the architectures are allowed to implement this as it suits them the most?"}}
